Xiaomi Robot Vacuum S40 delivers 10,000Pa of suction through a 5-in-1 cleaning system with anti-tangle technology and an integrated vacuum-and-mop function, guided by LDS laser navigation for precise mapping.

Its two-pass deep cleaning mode strengthens dust removal, and settings can be tailored per carpet through the Xiaomi Home app. With a 5200mAh battery rated for up to 180 minutes in standard mode, the S40 auto-docks and recharges as needed, and supports voice control via Alexa or Google Assistant.

As Xiaomi's more affordable S-series robot vacuum, the S40 keeps the essentials — solid suction, integrated mopping, and laser navigation — while skipping the self-cleaning dock and extendable arms of the Pro model. It suits buyers who want reliable daily cleaning without paying for maintenance automation they're happy to do by hand.
